Rod Mills for coarse grinding | FL

If the mill is restarted without first removing the hot coal, an explosion can occur when particles are suspended and exposed to the in-rushing combustion air. Even in routine mill shutdowns, there is a danger that any residual coal left within the mill will oxidise, and may explode as the mill is restarted.

The fineness of the milling product and the capacity of the pulverizer are strictly connected. With increased fineness grows the overall circulation rate of coal in the mill, coal retention time and the flow resistance. As a result, the maximum mill capacity decreases and the rate of change of operational parameters of the furnace system ...
